Commandline Interface (CLI)
The Forge CLI is the unifying command-line interface for the Candescent developer experience. It accompanies you through every phase of the developer journey — learn, build, integrate & test, operate, and scale — without leaving the terminal.
Forge is Candescent's umbrella brand for the developer experience. The CLI is one of the products under Forge, alongside the developer documentation portal, the Developer Console, and the SDKs. Throughout this guide, "the CLI" refers specifically to the Forge CLI.
What the CLI Does
The CLI is organized around the developer journey:
Learn
- AI-powered docs search —
forge askruns a streaming AI search across the Candescent developer documentation. Use it as a one-shot question or as an interactive REPL with follow-up suggestions. Requires an active session (forge login). - API discovery —
forge api listandforge api describebrowse the full Candescent Digital Insight API operation registry from the terminal, including parameter details and examples. - Template browsing —
forge widget templatesandforge aspect templatesshow every starter template, grouped by category, with previews of the generated code.
Build
- Widget scaffolding —
forge widget creategenerates a new web (Module Federation) or mobile (React Native) widget via Nx, with optional template overlays for common patterns (data charts, agent chat, promotional). - Aspect scaffolding —
forge aspect preview --template <id>(and optional--preset <id>) generates ready-to-edit Aspect code: classic UI patterns (banner, toast, modal, countdown), session-aware flows, vendor loaders and GTM-style snippets, mobile JSBridge chat shells, and related patterns. Output can be saved under./aspects/for local iteration. - Application & credential management —
forge app *andforge env *configure the credentials your code will need at runtime.
Integrate & Test
- Environment diagnostics —
forge doctorchecks Node, auth, git, Docker, and the extensibility monorepo; add--networkto verify Developer Console connectivity and token exchange after login. - API contracts —
forge widget api-contractandforge aspect api-contractdocument mock and production endpoint shapes for data-backed widgets and vendor presets. - Local previews —
forge widget previewandforge aspect previewlaunch a local OLB Docker playground (web) or an Expo + Metro Bundler sandbox (mobile) for instant feedback against a realistic banking shell. - Live API calls —
forge api call <tag>.<operation>executes any DI API operation from the terminal so you can validate integrations as you build them. - Mobile preview —
forge widget preview --platform mobileandforge aspect preview --platform mobileopen the Expo mobile sandbox for testing on a physical device (Expo Go), iOS Simulator, Android Emulator, or via Expo's tunnel mode.
Operate
- Submission workflow —
forge widget submitandforge aspect submitopen a structured pull request for review, with built-in lint checks (ESLint + TypeScript + markdownlint) and platform validation. - Submission tracking —
forge submission list,forge submission status, andforge submission dashboardgive you cross-cutting visibility into every submission and its review state. - Publish & deploy —
forge submission publishmerges the approved PR and triggers the CI deploy pipeline.forge submission deploypromotes a published component to production. - PR management —
forge widget submitandforge aspect submitcreate review PRs; useforge repo pr listandforge repo pr statusto inspect them from the terminal.
Scale
- Repository setup —
forge repo initprovisions your FI repository for extension development. - Collaborator management —
forge collaborator add / list / removemanages who on your team can submit and manage components. - Multi-environment workflows —
forge login -e <env>lets you switch between Sandbox and Production.forge env *manages SDK environment variables independently of the login environment.
Who Should Use the CLI
The Forge CLI is designed for two audiences:
Financial Institution Developers
FI developers who build custom widgets and Aspects to extend the Candescent Digital Banking platform for their customers. The CLI handles the full lifecycle: scaffold a project, preview it in a local playground, validate it against live APIs, and submit it through the GitHub-based review process.
Marketplace Partners (Fintechs)
Partners building integrations that multiple financial institutions can adopt. The CLI provides the same development workflow as FI developers.
Architecture
The CLI integrates with several Candescent services and development tools:
| Service | Used By |
|---|---|
Developer Console (console.candescent.com / console.sandbox.candescent.com) | login, app, aspect submit, submission, collaborator, repo, widget submit |
@cdx-forge/di-typescript-sdk | api list, api describe, api call (operation registry + live API calls) |
| GitHub REST API | repo pr, submission publish (requires gh auth or GITHUB_TOKEN) |
| Developer documentation search service | ask (streaming AI search across developer docs) |
Nx + cdx-extensibility-apps | widget create, widget preview, widget build (local scaffolding and builds) |
| OLB Docker Playground | aspect preview, widget preview (local banking shell with widget slots and Aspect injection) |
cdx-mock-data-apis (port 4010) | Chart-widget templates, forge widget preview for data-driven widgets |
cdx-mock-partners (port 4011) | Partner-vendor scenarios, Aspect previews that load remote vendor scripts (including iframe-sso handoff via mock partners) |
| Expo + Metro Bundler | widget preview --platform mobile, aspect preview --platform mobile (mobile sandbox via Expo Go, simulator, or tunnel) |
Related Packages & Resources
Public packages, container images, and source repositories you may use alongside the Forge CLI:
CLI distributions

@cdx-forge/cli(install withnpm i -g @cdx-forge/cliorpnpm add -g @cdx-forge/cli) - Homebrew tap —
candescent-dev/homebrew-forge(install withbrew install candescent-dev/forge/forge-cli)
SDKs and code references
- TypeScript Server SDK —

Sample apps and playgrounds
cdx-extensibility-apps— github.com/candescent-dev/cdx-extensibility-apps — sample web and mobile widgets/Aspects, plus theplayground/webandplayground/mobile-sandboxworkspaces thatforge widget previewandforge aspect previewuse under the hood. The CLI auto-clones this repo to~/.forge/cdx-extensibility-appson first use.
Local mock servers and dev infrastructure
- OLB Docker Playground (web preview shell) — base image:
ghcr.io/candescent-dev/olb-playground. The local compose file incdx-extensibility-apps/playground/webis configured so widget HTTP calls can reach the host on ports 4010 / 4011. cdx-mock-data-apis— github.com/candescent-dev/cdx-mock-data-apis — mock REST data server (port 4010). Used by the chart-widget templates (forge widget create --template data-chart) and any widget that calls alocalhost:4010/...URL via the SDK.cdx-mock-partners— github.com/candescent-dev/cdx-mock-partners — mock partner/vendor server (port 4011). Used by Aspect templates and presets that load remote vendor scripts (for exampleengagement-script-loader,iframe-sso).
Mobile preview prerequisites
- Expo Go — expo.dev/go (iOS / Android client for previewing mobile widgets and Aspects on a physical device)
- Xcode + iOS Simulator — developer.apple.com/xcode (macOS only)
- Android Studio + Android Emulator — developer.android.com/studio
Platform Support
The CLI supports both web and mobile development for widgets and Aspects:
| Extension Type | Web | Mobile |
|---|---|---|
| Widgets | Nx + Module Federation + OLB playground | Nx + React Native + Expo sandbox |
| Aspects | JavaScript IIFE injected into host page | HTML document loaded in a WebView |
The --platform flag (available on create, preview, and submit commands) ensures you build and submit for the correct target. Platform is recorded at create/preview time and validated at submit time.
Distribution
The CLI ships through two public channels, both updated automatically on every release:
- npm —
@cdx-forge/clifornpm/pnpmusers (any platform) - Homebrew —
candescent-dev/forgetap providing theforge-cliformula for macOS and Linux
